Dropbox sets up an app data backup API; now has 175 million users syncing 1 billion files a day

Drobpox is holding its first developer conference today dubbed DBX where the company’s CEO announced that the cloud storage service is now responsible for the files of 175 million users. They are syncing more than a billion files every day. Impressive, indeed.

Additionally, there are over 100,000 apps that use the Dropbox API set. More interestingly, It is getting updated with an interesting Datastore API, which will allow users to backup their application data, which means that settings, bookmarks, contacts, to-do lists and game scores can get backed up to the Dropbox cloud.

Our Sync and Core APIs already take care of syncing files and folders, but as people use mobile apps more and more, a lot of their stuff doesn’t really look like a file at all. With the Datastore API, we’re moving beyond files and providing a new model for effortlessly storing and syncing app data. When you use an app built with datastores your data will be up-to-date across all devices whether you’re online or offline. Imagine a task-tracking app that works on both your iPhone and the web.

We’ll see if developers of popular apps get excited about this functionality and whether we’ll see it in action at all soon.
